Audio Research D130 Stereo Power Amplifier
Manufactured by Audio Research, the D130 is a high-performance stereo power amplifier designed to deliver wide bandwidth, excellent control and low noise performance. Built around a robust solid-state output stage and a substantial power supply, the D130 was engineered to provide stable output across demanding loudspeaker loads while maintaining the transparency and musicality associated with Audio Research components.
With a rated output of 130 watts per channel into 8 ohms and 200 watts per channel into 4 ohms, the amplifier offers ample power for a wide range of loudspeakers. Its wide power bandwidth extending to 150 kHz, combined with high slew rate and low distortion performance, allows the D130 to reproduce musical transients with precision and clarity.
The amplifier also features both balanced and unbalanced inputs, high input impedance for easy system integration, and a well-regulated power supply incorporating substantial capacitance to maintain dynamic stability during demanding passages.
